    No full text
    This study explores the sustainable valorization of Annurca apple by-products by examining the polyphenolic content and antioxidant activity of peel, flesh, and core at two ripening stages. Ripening significantly enhanced the concentration of bioactive compounds, particularly in the peel, where total polyphenols increased from 124.4 to 423.3 mg of CAE/100 g FW, flavonoids from 18.2 to 51.3 mg of quercetin equivalents, and orthodiphenols from 11.9 to 36.1 mg of CAE. The flesh and core showed more moderate increases. Antioxidant activity, assessed using five in vitro assays (DPPH, ABTS, FRAP, TAC, and H2O2), was consistently highest in the peel, especially in the ABTS assay. Although the flesh had fewer phenolics, it showed a 1.5-fold increase during ripening, accompanied by improved antioxidant performance. The core also proved notable antioxidant potential, particularly in ripe samples. UHPLC-MS/MS analysis identified 11 phenolic compounds, showing tissue- and ripening-specific distribution. SDS-PAGE revealed a ripening-related increase in Thaumatin-like Protein 1a (TLP1a), especially in the core and flesh. Its association with tissues showing high antioxidant ability suggests a possible role in enhancing the bioactivity of polyphenol-rich extracts. From an agri-food waste valorization perspective, the peel and core represent promising sources of bioactive compounds for developing functional foods and nutraceuticals

    No full text
    Background: Patient education (PE) is an integral part of treatment from taking charge to the care, assistance, and rehabilitation of the patient, and consists of structured, organised actions, the orientation of which is aimed at finding solutions supported by scientific evidence. Aim: This prospective, descriptive, exploratory, single-centre pilot study aimed to evaluate the effectiveness of a PE intervention for oncological patients with entero-urostomies and their caregivers through the measurement of quality of life, perceived needs, and caregiver burden. Methods: This study was conducted in a National Cancer Institute between 22 December 2022 and 31 March 2023, and it was organised into three specific therapeutic education event days relative to the real needs measured by the patients and caregivers before it. Results: Our results seem to suggest that the PE intervention in entero-urostomy patients improves their quality-of-life levels, while caregivers’ perceived emotional burden levels are reduced. Conclusions: Targeted and individualised PE interventions positively affect self-care and quality of life in patients with an entero-urostomy and the emotional burden perceived by caregivers

    Living a sea change: The role of embodiment in enacting a real utopia

    No full text
    Real utopias are visions of desirable futures that are both aspirational and achievable. As a form of projective agency, they can inspire experimental enactment, in which utopian ideas are tested in real-life contexts. Although earlier research has touched on the practical and visceral experiences associated with such experimental enactment, it has surprisingly undertheorized the role of embodiment therein. Our shared experience of the Sailing Initiative, a collective endeavor to sail to a scientific conference on an island, provided a unique opportunity to explore the role of the body in bringing a real utopia to life. In the Sailing Initiative, we experimentally enacted our shared vision of environmental sustainability and slow academia, aiming to travel to the conference in a sustainable way while using the travel time for slow-paced academic work in an unconventional setting. We extensively documented our expectations and experiences through individual and collective reflections before and after the journey, as well as through photos and videos. Based on an abductive analysis of the rich autoethnographic data, we develop a theoretical model of the role of embodiment in enacting a real utopia that is sensitive to material realities. We argue that viewing agency through the lens of embodiment is significant for three reasons. First, an embodiment perspective highlights the transformative potential of experimental enactment in unconventional settings, helping individuals and collectives overcome embodied institutional norms and create new practices. Second, the body is not merely an instrument for executing envisioned practices or enduring discomforts; rather, bodily experiences continuously shape concrete actions in the process of enacting a desired future. Third, given the importance of bodily memories in crafting shared narratives of desired futures, a real utopia should be viewed not only as visionary thinking but as a projection shaped by both past and present bodily and visceral experiences

    Sul rapporto tra rinuncia agli atti e accettazione della parte (non ancora) costituita

    No full text
    Il lavoro analizza l’istituto della rinuncia agli atti, soffermandosi in particolare sul rapporto con l’accettazione e sviluppando, altresì, una riflessione in merito alla disciplina dell’art. 473 bis. 21 c.p.c., operante nel nuovo rito familiare e minorile. In particolare, ai fini dell’estinzione del processo, l’interpretazione costante dell’art. 306 c.p.c. prevede che l’accettazione del convenuto sia necessaria solo quando questi sia già costituito, mentre sarebbe superflua ove non lo sia ed anche in pendenza del termine per la costituzione tempestiva. Ci si chiede allora se sia possibile fornire una lettura differente, e ritenere necessaria l’accettazione del convenuto anche in tale ultima fattispecie

    Carbonatogenic Bacteria from Corallium rubrum Colonies

    No full text
    The precipitation of minerals, in particular carbonates, is a widespread phenomenon in all ecosystems, where it assumes a high relevance both from a geological and biogeochemical standpoint. Most carbonate rocks are of biological origin and made in an aquatic environment. In particular, bioprecipitation of carbonates is believed to have started in the Mesoproterozoic Era, thanks to a process often driven by photosynthetic microorganisms. Nevertheless, an important contribution to carbonate precipitation is also due to the metabolic activity of heterotrophic bacteria, which is not restricted to specific taxonomic groups or to specific environments, making this process a ubiquitous phenomenon. In this framework, the relationship between carbonatogenic microorganisms and other living organisms assumes a particular interest. This study aims to isolate and identify the culturable heterotrophic bacterial component associated with the coenosarc of Corallium rubrum in order to evaluate the occurrence of strains able to precipitate carbonates. In particular, the study was focused on the identification and characterisation of bacterial strains isolated from a coral coenosarc showing a high carbonatogenic capacity under laboratory conditions. Samples of C. rubrum were taken in the coastal waters of three Italian regions. The concentration of the aerobic heterotrophic microflora colonising C. rubrum coenosarc samples spanned from 3 to 6∙106 CFU/cm2. This variation in microbial populations colonising the C. rubrum coenosarc, spanning over 6 orders of magnitude, is not mirrored by a corresponding variability in the colony morphotypes recorded, with the mean being 5.1 (±2.1 sd). Among these bacteria, the carbonatogenic predominant species was Staphylococcus equorum (93% of the isolates), whereas Staphylococcus xylosus and Shewanella sp. accounted only for 3% of isolates each. All these strains showed a remarkable capacity of precipitating calcium carbonate, in the form of calcite crystals organised radially as well crystalised spherulites (S. equorum) or coalescing spherulites (Shewanella sp.). S. xylosus only produced amorphous precipitates of calcium carbonate. All bacterial strains identified were positive both for the production of urease and carbon anhydrase in vitro at 30 °C. It seems that they potentially possess the major biochemical abilities conducive to Ca2+ precipitation, as they showed in vitro. In addition, all our carbonatogenic isolates were able to hydrolyse the phytic acid calcium salt and then were potentially able to induce precipitation of calcium phosphates also through such a mechanism

    Mediterranean Diet and Agri-Food By-Products: A Possible Sustainable Approach for Breast Cancer Treatment

    No full text
    The sustainable use of agri-food by-products offers a significant opportunity. Increasing evidence shows that these by-products have various bioactive compounds that help reduce inflammation and, in turn, the severity of several proliferative diseases. Numerous epidemiological studies have suggested an inverse relationship between the consumption of fruits and vegetables and the incidence of breast cancer. Anti-breast cancer effects involve a variety of mechanisms, inhibiting proliferation, migration, metastasis, and angiogenesis of breast tumor cells; inducing apoptosis and cell cycle arrest; and enhancing the sensitivity of breast tumor cells to radiotherapy and chemotherapy. Extensive research suggests that the Mediterranean diet has various bioactive compounds known to provide protective effects against a wide range of non-communicable diseases. Among the phytochemicals identified as protective against breast cancer, natural polyphenols have shown antioxidant, anti-inflammatory, immunomodulatory, and anticancer properties. This review highlights the potential role of natural dietary products and their primary bioactive components in preventing and treating breast cancer, with special emphasis on the mechanisms of action. The integration of agri-food by-products into the diet not only offers opportunities for the prevention and treatment of breast cancer but also promotes sustainable use of resources, contributing to the reduction of waste and the improvement of global health

    Microplastic pollution from pellet spillage: Analysis of the Toconao ship accident along the Spanish and Portuguese coasts

    No full text
    In December 2023, 25 tons of pellets were lost by the Toconao ship in the Northwest Atlantic Ocean in front of the Portuguese coast. In this work, a coastal stretch of 633 km in Asturias and Galicia (Spain) and Northern Portugal was investigated to assess pellets' concentration on 31 beaches. Field surveys were carried out in March 2024 and focused on sampling plastic pellets deposited along the shoreline. All the 7263 sampled pellets were characterized by size, degradation level, and color, while one subset was characterized by weight (40 % of the total) and another subset by polymer type (15 % of the total) using FT-IR spectroscopy. The results reveal that 94 % of the surveyed sites containing pellets, whereas the concentration values vary significantly among beaches, ranging from 0 to 40.3 pellets/kgdw. By combining the accounted variables, it emerges that 48.0 % of the collected pellets can be linked to the Toconao spill
